[jennie77]

Thank you for your previous clear grammar explanation. It really helped me a lot.
And I have another question here.
SO, please help me.


The sentence is this.

He has become a self-starter and, once started, wishes to continue in his own way.

What do people think is omitted in the highlighted phrase?
Which one Is the original sentence, "once it is started" or "once he gets started"?

If the original sentence is "once he gets started", can we omit the subject and verb like "gets" here?

I'd say that "once started" does mean the same as "once he gets started"; possibly the more direct equivalent, though with the same meaning, is "once he is started", i.e. as a self-starter, once he has started himself.
